Hi,
I am trying to run a linux commands from a java app.The below code works for executing windows commands in java application,but how can i do in Linux. Please help me it very urgent.

Thanks,

try
{
String osName = System.getProperty("os.name" );
System.out.println(" OS NAME is "+osName);
// String[] cmd = new String[3];

if( osName.equals( "Windows 2000" ) )
{
cmd[0] = "cmd.exe" ;
cmd[1] = "/C" ;
cmd[2] = args;
}
Runtime rt = Runtime.getRuntime();
System.out.println("Execing " + cmd[0] + " " + cmd[1]
+ " " + cmd[2]);
Process proc = rt.exec();
// any error message?

Well - that depends on the command to run of course.
I.e.:

public class CmdRun
{
        public static void main (String args[]) throws java.io.IOException
        {
                Runtime rt = Runtime.getRuntime ();
                Process proc = rt.exec (args);
        }
}

run it like that:

java CmdRun  /usr/bin/X11/xterm -e /usr/local/bin/acroread /home/stefan/daten/texte/aec_FE_2003_Reas_en.pdf

btw.: OS NAME is Linux

The equivalent of "cmd /c" is "sh -c". A command line like

sh -c "foo > outputfile < inputfile"

lets that last argument be interpreted by the shell as if it were typed at the shell prompt.
